Leading Mobile App Development Frameworks in 2021


Mobile apps have become simply a part of daily life. From contact (Whatsapp, Facebook) to food delivery (Zomato, Swiggy) to Uber and e-commerce (Amazon). The daily lives of people in rural and urban areas have been changed by using popular software.

Mobile app development is a multi-layer process, and tech developers have been seeking to uncomplicate this process with an easy-to-use ADF or application development framework.

What is an app development framework?

It is an assistive platform for developing applications. ADF exists to make it quicker, more straightforward, and uncomplicated to build applications. We are going to cover the top mobile app development frameworks to consider before creating an app.

Mobile application development systems deploy visual, declarative ways to circumvent the writing of time-intensive codes from scratch.

This means that mobile app developers will drag and drop to widely used simple codes to avoid building apps from the start. Frameworks streamline the development of apps and can consist of the following elements-

  • Predefined classes and functions
  • code Libraries 
  • Compiler 
  • Managing hardware systems
  • Interacting with system software
  • Assistant services to help develop software

Companies typically outsource mobile apps’ development because of their current technology stack and use the most suitable development framework.

Best Frameworks for Mobile App Development 2020-21

Now, we’ve put together a list of the best frameworks for mobile app development of 2020-2021. Let’s take a look!

React Native is one of the common cross-platform frameworks introduced by Facebook. Supported by colossal community support, React Native is developed on top of the ReactJS, which gave massive competition to the long-time favorite, AngularJS.

It helps developers build JavaScript-only mobile apps that are compatible with iOS and Android platforms. This framework constructs a hierarchy of UI components to generate the JavaScript code. Some of the Respond Native apps are Facebook, Airbnb, Walmart, Bloomberg, Instagram, Soundcloud, and UberEats.

Here are some of the advantages of using React Native for mobile app creation that you can bear in mind:

  • Optimum efficiency
  • The modular design of the architecture
  • Efficient Code
  • Reusability of Code
  • Large community
  • Support of third-party plugin
  • Hot support for reloading
  • User-friendly solutions and repositories
  • Integrated to the NPM (Node Packet Manager)
  • Live reload feature: the first is for code modification, and the second is to preview the modified changes.

2. Flutter

Flutter is a free, open-source mobile UI platform developed by Google. Flutter can be summarised in a few words as a platform that enables developers to build a single-code native mobile app. This means developers need to use one programming language and one codebase to build two applications, i.e., iOS and Android.

According to Google, “More than 2 million developers have used the Flutter framework in the last two years of its release, and it is growing steadily.” Moreover, Google saw 10 percent monthly growth in March, with nearly half a million developers using Flutter every month.

It is used to develop native Android and iOS apps from the same code base. It has been around since 2015, when Google launched it and stayed in the beta stage before its official release in December 2018.

Flutter helps users build applications for cell phones, televisions, tablets, wearables, smart displays, etc.

Reasons why Flutter can be an option for developing mobile apps

Faster App Development with Hot Reloading: Flutter is one of the cross-platform frameworks for rapid app development. This is because Flutter has native codes and features such as “hot reloading” or “hot restart” that allow developers to display code changes within a second; thus, it improves developers’ productivity by tenfold.

Flutter-based apps are mostly dependent on built-in widgets but not on platform widgets. As a result, the app size can be measured at almost 4MB. Flutter comes with a wide variety of widgets, including navigation, scrolling, and fonts. This offers a native performance experience on both platforms, i.e., iOS and Android. Developers can also easily save time on creating mobile applications.

Multiple IDE Support: No matter how complicated and broad you want an app, Flutter has recently become the developer’s top option. The reason for this is excellent multiple IDE support, which results in a convenient atmosphere for developers to build a cross-platform app.

Generally, when developers start operating with an IDE, they do not prefer to move to another IDE. This is where Flutter takes momentum and gives access to an extensive range of IDEs, including Android Studio, IntelliJ, VC Code, etc.

The name of the standard apps used in the Flutter app creation system is:

  • Alibaba
  • Google Ads app
  • Reflect
  • Cryptograph
  • Birch Finance

3. Ionic’s

Ionic is considered one of the best mobile app development frameworks and a common open-source framework for developing cross-platform mobile apps using web technologies such as HTML, CSS, and JavaScript. The system provides mobile-optimized components and native APIs that use Cordova and Ionic Native. Written in the TypeScript language, Ionic has the crucial benefit of its models. It is a multi-purpose application that helps create hybrid apps, progressive web apps (PWAs), and cross-platform apps. Its user-friendly features make Ionic a desirable platform for mobile app growth.

Features & Explanations Ionic is the best framework:

Beautiful Default UI that is easy to customize: Ionic comes with a multitude of default JavaScript and CSS components that cover most of the primary stuff you would like to create into a mobile app. It contains components such as a sliding menu and other items such as:

  • Buttons
  • Lists
  • Navigation
  • Form Inputs
  • Tabs
  • Sliding boxes

Also, the themes and components present in the Ionic framework are adjustable, providing more flexibility to construct an app interface.

Cordova Plugins: The availability of Cordova plugins offers access to features such as flashlight, camera, GPS, and more.

Ionic is based on Angular: if you have ever used the Ionic system, you already know that Ionic is built on the Angular framework. Ionic is expanding Angular with a bunch of stuff to build Angular mobile applications seamlessly. Google backs Angular, but it does not inherently mean it is best for every situation; nevertheless, several smart engineers are building and sustaining it. It is a pretty good bet, then!

Vast and Supportive Community:

Ionic has undeniably the most fantastic sense of community any developer has ever had in the past. It is all part of such a big, supportive, welcoming group.

Also, there is often an ongoing blog post, which supports members with the forums’ support. Users can also try posting app questions on social media, and you never know; you could get all the answers to your queries from the Ionic Framework’s creators.

The widespread applications developed using the Ionic framework are:

  • Diesel
  • McDonald’s Turkey app
  • JustWatch
  • Mclaren Automotive
  • Sworkit

4. PhoneGap

PhoneGap was first called “Apache Cordova,” introduced by Nitobi. After that, Adobe bought Nitobi and called it “PhoneGap.” It is a commonly used technology for the production of cross-platform mobile applications. Or we can claim that it is a comprehensive mobile app development system for cross-platform applications. The best part of this framework is that it eliminates complex languages like Java for Android and Swift for iOS.

PhoneGap aims to close the gap between hybrid and native mobile applications. It lets developers create hybrid apps targeting all devices using web-based languages such as HTML5, CSS3, and JavaScript.

  • Adobe Systems powered this framework, but now it is handed over to Apache to manage and keep it available.

It often helps developers write a single app installed through several channels as a native app.

The name of the applications created using the Mobile App Platform of PhoneGap:

  • Wikipedia
  • HealthTap
  • The DHS Program
  • TripCase

Benefits of using the PhoneGap framework:

  • Open Source: this platform can be used free of charge.
  • Plugin friendly: supports a range of helpful plugin integrations, accessible via the Adobe repository, the public git repository, and the Node JavaScript framework.
  • Skilled developers are not required: because PhoneGap uses popular and standard technologies such as JavaScript, CSS3 & HTML5, developers do not need specialized expertise.

5. Xamarin

Launched by Microsoft, Xamarin is one of the most robust hybrid application frameworks supported by the C programming language. Xamarin, an open-source framework, is used to create hybrid mobile applications using.NET and C#. Besides, this comprehensive multi-platform development system has over 60,000 developers and contributors, outstanding customer service, and detailed documentation as a Microsoft software.

When it comes to the perfect, cost-effective system, Xamarin helps save money by developing three single-code applications or platforms, i.e., iOS, Android, and Windows.

Features & Reasons for Xamarin’s Success:

Seamless UI Development: With the aid of Microsoft Visual Studio and Xamarin Studio, designers can create beautiful interfaces and enhanced user experience.

Multi Library Support: In contrast to React Native, this framework also allows encoders to use CSS libraries.

Best suited for offline applications: Xamarin is best suited for developing offline apps. This is because there are many situations where the program has to work without using the Internet.

The following applications made with the use of Xamarin are:

  • The World Bank
  • BBC Good Food
  • HCL
  • Alaska Airlines
